.NET and matching element name with wildcard using XPath

This is similar to matching a name space with a wildcard.

'This is the node we are searching in
Dim someXmlNode As XmlNode = FetchXmlNode() 
Dim xPathExpr As String = String.Empty
'find all nodes with names that starts with nisse_
xPathExpr = ".//*[starts-with(name(), 'nisse_')]"
'loop through all elements that matches our XPath
For Each elementWithNisse As XmlNode In someXmlNode.SelectNodes(xPathExpr)
